How to find the distance of beacon using receiver RSSI value?

Hi, I am doing a project based on beacon tracking. For that, I have to detect the beacon and find the RSSI of received beacon using STM32WB board. Is there any possibilities to find out the RSSI value? and how can approximate the distance between both using RSSI?

Hi Kryptons,

Please take a look at the STM32CubeWB firmware package under \Projects\$Board_name$\Applications\BLE

Hope this is helpful.

Best Regards,

Ons.

Hi Ons,

Thanks for your reply.

I already went through that example. But I was unable to find anything related to RSSI. Can I get any documents related to that topic ?

Hi Kryptons,

Yes for sure,

I think these links are hopeful for you (especially the second one 🙂 :(

  1. AN4971: Received signal strength indicator (RSSI) for ST25RU3993
  2. AN5508: Social Distancing Detection using Bluetooth® Low Energy

Hi Ons KOOLI,

I am also doing Beacon project and using your example BLE_MeshLightingPRFNode

I get signal of beacon tag by function callback BLEMesh_CustomBeaconReceivedCallback, data is true but value rssi still 3 and it doesn't change

How can i fix it?
